In "Emergent Gravity and the Dark Universe," Verlinde mistakenly used a wrong relation $\Phi_B(r)=GM_B(r)/r$ to derive one of his equations. Of course, a correct relation is $\Phi_B(r)=\int GM_B(r')/r'^2 dr'$. This makes the equation that he derived not valid. If this equation is nevertheless correct, his earlier equation from which he derived it is wrong. 


Emergent Gravity and the Dark Universe

Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter
